Bongosso (or Bougounso) is a village and seat (chef-lieu) of the commune of Koromo in the Cercle of Koutiala in the Sikasso Region of southern Mali.[1] The village is northeast of Koutiala.
French explorer René Caillié stopped at Bongosso in February 1828 on his journey to Timbuktu. He was travelling with a caravan transporting kola nuts to Djenné. He described the village in his book Travels through Central Africa to Timbuctoo published in 1830. He wrote:
About eleven in the morning we arrived at Bancousso [Bongosso], a large village containing a population of five or six hundred, and situated in a well cultivated plain, shaded by baobabs. This village has a large market, well supplied with the productions of the country; I saw in it a great quantity of cloth and earthen pots which are made here.
